PDF Bookmark Lister

List all the bookmarks — the outline — inside a PDF, so you can see its structure at a glance.

The table of contents behind the document

Well-made PDFs carry an outline of bookmarks — the clickable structure that lets you jump to a chapter or section in a reader's sidebar. This pulls that outline out and lists it, so you can see how a document is organised, check that the bookmarks are complete, or map out a long file before you dig into it.

Open the PDF and its bookmark structure is laid out for you.

What an empty list tells you

If the list comes back empty, the PDF simply has no bookmarks — plenty of documents, especially scans and quick exports, never had an outline added. That is useful to know in itself: a long PDF with no bookmarks is hard to navigate, and if it is one you are producing, adding an outline would make it far friendlier to read.

How to list the bookmarks in a PDF

Add the PDF.
See its bookmark outline — the built-in table of contents — laid out as a list.
Use it to check the document's structure or navigate quickly.

See the document's skeleton

Bookmarks (the outline panel in a PDF reader) are how long documents let you jump to a chapter. Listing them shows the whole structure at once, which is handy for auditing a report's organisation or confirming a table of contents is complete.

A document with no bookmarks lists nothing — many exported PDFs simply never had them added.
